> This is like saying I can fix global warming by recycling better and going vegan.

I can't agree. I don't think anyone who is diligent about recycling or making environmentally conscious food choices believes it will fix global warming. But doing the things that we can is still important for changing culture over time.

If you're a young person growing up in a home that thinks about these things responsibly, the hope is that more people reaching adult-hood will think about the world through that lens. Is it enough? No. Is it still critical? I think so.

> I've had managers who tried. None of them lasted at these companies that did not care.

I've worked at places where management did not behave in the way you describe. The point being that such places exist, and such an outcome is not so impossible.

One way to guarantee things will not change is to do nothing.
